Ed Stainless stands out as a top-notch manufacturer and supplier of high-quality Stainless Steel 317 Nuts, proudly based in Houston, USA. Known for their precision engineering and unwavering commitment to quality, Ed Stainless provides a wide array of SS 317 nuts tailored for various industrial needs. With cutting-edge manufacturing facilities and a strong emphasis on customer satisfaction, the company guarantees that every product meets international standards. Clients across the petrochemical, marine, and construction sectors in the USA and beyond trust Ed Stainless for their corrosion-resistant, durable, and high-performance stainless steel fasteners.
Stainless Steel 317 Nuts are primarily made up of chromium (18–20%), nickel (11–15%), and molybdenum (3–4%), along with trace amounts of carbon, manganese, silicon, sulfur, and iron. This unique chemical makeup gives them exceptional resistance to corrosion and impressive strength at high temperatures. On the mechanical side, SS 317 nuts boast a tensile strength of about 75,000 psi, a yield strength of 30,000 psi, and remarkable elongation properties. Their austenitic structure enhances creep resistance and stress rupture characteristics, making them perfect for tough environments. Plus, the alloy offers excellent formability and weldability, which are essential for industrial fastening tasks.
